Irritation to the undercarriage of the female breast due to the combined effects of environmental heat, tight under garments and dim titties being plump AF.

Common Side Effects: Tender red patches in the folds of the breast, tit zits, chest wetness, a general sense of irritability.

Not so rare, serious side effects: Placing any absorbent material in the cleavage crook, going braless in the office, asking for a divorce.

When to call a Doctor: Serious consideration of a breast reduction.
